[The interrelationship between lung functional disorder and blood transfusion]

Interrelationship was studied of the haemotransfusion volume with the purpose of correcting the oxygen-transport to functional inadequacy of the lungs, inadequate patency of the organ's vessels in patients presenting with abdominal haemorrhage. Transfusion of donor blood was accompanied in some cases by pulmonary function disorders manifested by development of pneumonia. The larger the volume of haemotransfusion, the higher probability for lung function impairement. But we failed to find an immediate association between the volume of the donor blood transfused, blood flow and ventilation in the lungs. A conclusion was drawn to the effect that there exist secondary mechanisms of injury to the organ and development of pneumonia. Of these, weakening of immunologic resistance because of donor blood is considered to be most probable mechanism contributing to the above injury.
